IMPLEMENT FOR CUTTING BUTTER FROM FIRKINS.

Speccation of Letters Patent No. 8,947, dated May 11, 1852.

To all whom it may concern:

VBe it known that I, NATHANIEL WOOD- BURY, of Salem, in the county of Essex and State of Massachusetts, have invented a new and Improved Implement for Cutting and Vithdra-wing Butter from Tubs, Fir* kins, &c.; andI do hereby declare that the following is a full, clear, and exact description of the construction of the same and the manner in `which it is operated,'refer ence being had to the annexed drawings, making a part of this specication, in whichi Figure l, is a side view of the implement showing one of the two levers by which the knife is operated. F ig. 2, is a side view of ditto, the side of the box or case being removed, showing the piston, knife, and a portion of the two levers by which the knife is operated. Fig'. 3, is an end view of ditto.

Similar letters of reference indicate corresponding parts inV each of the several figures.

The nature of my invention consists in providing a rectangular box having a narrow knife which traverses over one of its ends, said knifebeing operated by two levers having their fulcra on two of the sides of the box or case, these levers will be fully described hereafter, there is a piston within the box having suit-able rods which project through one end of the box and by these the piston is operated, the implement is used. by forcing the end of the box or case into the butter the required distance. the piston having been previously raised or drawn back, and then operating the levers, so that the knife traverses across the end of the box, -cutting the butter, and thus detaching the butter that is within the box or case from that which is within the firkin` or tub, the box or case is `then withdrawn and the butter within it forced out upon a plate or salver by means of the piston.

To enable others skilled in the art to make and use my invention, I will proceed to of the box orcase, seen more particularly in Fig. 2, the extreme ends of the knife fit in grooves (b) (b) in two of the sides of the box nearr their ends, the knife passing through slots in the ends of the levers D, D, a part of which levers are seen in Fig. 2, the extreme ends of the knife which t in the grooves (b) are bent upward as seen by the dotted lines in Fig.` 3, these bent ends prevent the knife from turning, and thus the cutting edge of the knife always faces in the proper direction; (c) (c) are the fulcra of the two levers D, D, these fulcra are pins which are attached to two of the sides of the box, a pin fitting in an.

oblong slot in each lever, the oblong slo-t and pin of one lever is distinctly seen in Fig. l.

E, is a bent wire attached to the ends of the two levers the wire E, serving as a handle to operate the levers and consequently the knife.

Now it will be seen that when the ends of the levers D, D, are drawn downward the knife C, attached to the o-pposite ends will be thrown upward and as the knife travels in a straight or direct line owing to its extreme ends fitting in the slots (ZJ) (b) which are perfectly straight, the levers D, D, will be forced or pushed inward as the knife is raised, and hence the object of the oblong slots in the levers viz., to allow the knife to operate in a straight line, to illustrate this more fully suppose the levers to be in the position represented by the black dotted lines in Fig. l, the knife being at the bottom of the end of the box, now if the handle E, be pulled downward the knife will raise, and when it reaches the center of the end of the box or case A, as seen by the dotted red lines, the pins or fulcra (c) will be nearly or quite at the extreme end of the slot, as the levers pass above the center of the end of the box, the levers are drawn forward and when the knife C, reaches the top of the end of the box or case the pins or fulcra (o) will be about in the center of the oblong slot as seen by the blue dotted lines in Fig. l, the operation of the knife and levers will thus be clearly seen.

The levers are not exposed in the inner side of the box orcase, but are covered by strips of metal (al) (al) see Figs. 2 and 3, the levers being placed between the side-s of the case or box A, and the strips of metal (d) just mentioned; there are two plates or triangular pieces (e) (e) see dotted lines Fig. 1, secured just above and below each lever D, and between the sides of the box or case and the metal strips (d) which prevent the pins from getting out of the oblong slots, and at the same time do not interfere with the operation of the levers.

The several parts being now described the manner in which the implement is operated will be readily seen; the knife C, is first placed at the bottom of the end of the box or case A, in the position as shown by the black dotted lines in Fig. l; the piston B, is then drawn to the end of the box or case opposite to that at which the knife is placed, the end of the box or case at which the knife is placed is then forced or pressed by the aid of the handle F, attached to the box or case, into the butter the required distance, the handle E, of the lever is then` pulled in the proper direction and the knife traverses across the end of the box or case dividing or separating the butter that is within the box or case from that which is within the rkin or tub; the box or case is then withdrawn, and the butter within it forced out by operating the piston B.

If the butter is to be taken out of the center o-f a tub or irkin there should be four sides to the box, but if the butter is taken from the side of the irkin adjoining the staves a three sided box would answer; a

draws out the butter in neat square bars, ink

many cases butter can not be taken from the irkin or tub in a neat manner, especially when hard, another advantage of my implement is that a graduated scale may be stamped or engraved upon it so that a person may draw out anyT given quantity he pleases, say a pound or five pounds.

Having thus described the nature of my invention and the manner in which it is operated, what I claim as new and desire to secure by Letters Patent, is-

The knife C, operated by means of the levers D, D, or their equivalents in combination with the piston B, and the box, the knife, levers, and piston being constructed, arranged and operated in the manner and for the purpose substantially as herein shown and described.
